EXPLOSIVE COMPOUND.

SPECIFIGATION forming part of Letters Patent No. 289,760, dated December4, 1883.

Application filed August 1, 1883.

To all whom it may concern.-

Be it known that I, SILAS R. DIVINE, 0 Loch Sheldrake, Sullivan county,State of New York, .and a citizen of the United States, have invented anImproved Explosive Compound, of which the following is a full, clear,and exact specification.

My invention consists in an explosive compound, chiefly for blastingpurposes, composed of a solid ingredient-such as chlorate of potash-anda liquid ingredientsuch as oil of turpentinethe said ingredientsbeinginthemselves incapable of being exploded by percussion, and, whenmechanically united, forming the explosive- The theoretical proportionsin which the ingredients of my explosive combine most effectively areabout eight and one-third parts of chlorate of potash to one part ofturpentine; but inasmuch as turpentine possesses a strong aifinity foroxygen, it may be desirable sometimes, when said turpentine, which isaged or hasb'een more or less exposed to the air and has thus becomeoxidized, is employed as the liquid ingredient, to avoid an unnecessarypreponderance,. and hence waste, of oxygen in the finally-preparedcompound by decreasing the (No specimens.)

proportion of the chlorate of potash, and thus varying somewhat from theexact theoretical proportions as stated.

It will be understood that either perchlorate or permanganate of potashmay be employed as the solid ingredient of my compound.

The ingredients of my compound being in explodible by themselves bypercussion, they may be separately handled and transported with safety,and the'consumer can unite them, when and where it is desired to use theexplosive, by either mixing them in measured proportions in a suitablevessel or by simply causing the solid to absorb the liquid.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The described explosive compound, composed of a solid ingredientconsisting of chlorate of potash, and a liquid ingredient consisting ofturpentine, mechanically united, substantially in the proportions and asand for the purposes specified.

SILAS R. DIVINE.
